FAQs on Microbes in Human Welfare Video Lecture - Crash Course for NEET
| 1. What role do microbes play in human welfare? |  |
Ans. Microbes play several crucial roles in human welfare, including their use in the production of food and beverages (like yogurt and cheese), in medicine (such as antibiotics and vaccines), in agriculture (by enhancing soil fertility and plant growth), and in environmental management (like bioremediation to clean up pollutants).
| 2. How are microbes used in the production of antibiotics? | |
Ans. Microbes, particularly certain fungi and bacteria, are used to produce antibiotics through fermentation processes. For example, the mold Penicillium notatum is used to produce penicillin, which helps in treating bacterial infections. These microbes undergo controlled growth conditions to extract the antibiotic compounds.
| 3. What is the significance of microbes in agriculture? | |
Ans. Microbes are significant in agriculture as they help in the decomposition of organic matter, which enriches the soil with nutrients. Certain beneficial bacteria and fungi form symbiotic relationships with plants, enhancing nutrient uptake and promoting plant growth. They also help in controlling pests and diseases naturally.
| 4. Can microbes be used for waste management? | |
Ans. Yes, microbes are extensively used in waste management through bioremediation. They can break down toxic substances and pollutants in the environment, such as oil spills, heavy metals, and pesticides, converting them into less harmful forms. This process helps in cleaning up contaminated soil and water.
| 5. How do microbes contribute to food production and preservation? | |
Ans. Microbes contribute to food production through fermentation processes that enhance flavors and preservation. For instance, yeast is used in baking and brewing, while lactic acid bacteria are important in fermenting dairy products like yogurt and cheese. These processes not only improve taste but also extend the shelf life of food products.
